Doctor says change in your fingernails could hint if you've already had Covid-19


A doctor has said a change in the appearance of your fingernails could hint that you’ve already had coronavirus.

Dr Karan Raj has racked up million of followers on TikTok by posting informative videos and life hacks to his viewers, tackling everything from sleep tips to bizarre medical facts.

In a recent video, the doctor said that a condition called Beau’s lines can show if you’ve recently experienced an infection or trauma, and says scientists have reported that it’s commonly found among people recovering from covid.

He shows a picture of someone’s fingernails with a white line running horizontally across the width of the nail with a prominent ridge, but reminds viewers that it can be caused by a variety of factors and is not an accurate test to tell if you’ve had coronavirus.

The doctor clarified in the comments that it can have many causes and advises that the best way to find out if you’ve had Covid-19 previously is to take an antibody test.

Dr Raj says: “If you have something like this on your nails, it could be a sign you’ve had Covid.

“Scientists have noted that went patients recover from Covid, they are left with a clear or white horizontal line that leaves a prominent ridge on the nails.

“It’s known as Beau’s lines and it happens where there is a temporary interruption in nail growth when the body has an infection.

“It’s actually pretty harmless and can be caused by any illness or trauma to the body, not just Covid.

“Although we’re seeing it in more Covid patients, it’s not diagnostic of Covid and the best way to know if you’ve had Covid is an antibody test.”

The video has been viewed more than 1.6 million times and racked up more than 1,800 comments as Dr Raj responded to people saying they thought the lines were caused by an iron or zinc deficiency to reiterate it can be caused by a wide range of factors, with Covid-19 being just one.

He added: “The lines might stay for several weeks/months after infection but will then disappear as the nail grows.”
